Power-monitoring units
Circuit Monitor Series 4000
Functions and characteristics (cont.)
Input/output blocks may be added to the Circuit Monitor to:
b monitor the electrical installation, notably the status of the circuit breakers, and
check discrimination between protection devices
b measure the consumption of other commodities by counting the pulses sent by
water or gas meters
b measure the temperature of the transformers
b transmit parameters over analog channels to other systems
b etc.
The Circuit Monitor may be equipped with a total of 25 optional digital or analog input/
outputs.
These input/outputs may be added in two different manners:
b either using an IOC44 card
b or the IOX input/output extender module and individual input/output modules that
connect to the extender.
All these options may be installed in the field. Status changes on the digital inputs
are time-stamped to within the millisecond.

IOC44 card
This is an input/output card equipped with:
b 4 digital inputs 20 - 138 V AC/DC
b 4 digital outputs, including 3 relay outputs and a static output that may be
programmed as a pulse output. It may be installed in the option-card slots of the
Circuit Monitor.
There are three possible configurations:
b 1 IOC44 card
b 2 IOC44 cards
b 1 IOC44 card and 1 Ethernet ECC21 card.

IOX input/output extender
The IOX input/output extender may be equipped with up to eight plug-in input
or output modules. The entire unit connects to the side of the Circuit Monitor.
The input/output modules may be digital or analog.
Three pre-equipped versions may be ordered directly, the IOX08, IOX0404 and
IOX2411. Other versions may be user prepared by ordering an empty IOX extender
and separate I/O modules (see the section on I/O Modules for selection). In this case,
the IOX extender may be equipped with up to a maximum of four analog modules.
Description
IOX extender Empty extender with eight slots for separate input and/or
output modules, digital or analog, with however a
maximum of four analog modules.
IOX extender equipped with two input/output modules. IOX08 extender IOX extender equipped with:
8 digital input modules 120 V AC

IOX0404 extender IOX extender equipped with:
4 digital input modules 120 V AC
4 analog input modules 4-20 mA
IOX2411 extender IOX extender equipped with:
2 digital output modules 60 V DC
4 digital input modules 32 V DC
1 analog output module 4-20 mA
1 analog input module 0-5 V
